I think Bitcoin ETF sits on a 50/50 chance to be approved yet but there's still a glimpse of light shining as one of the Commissioner Hester Peirce in favor of it, in a sense that she likes to open on US an nnovation approach that could contribute to greater development.
The new member of the commissioner dissent the decision of rejection of Winklevoss Bitcoin ETF with a 3 to 1 vote, stating that the rejection isnt fair and over jurisdiction since they only looked on the possible outcome that price will be manipulated.
Quoted from Her interviewed I think we have an important role to play telling the United States and the world that our capital markets are open to innovation, said Peirce. And thats what sort of drove my dissent last week and what really drove me to come back to the agency as a commissioner.
There's no timeline when the voting will commence and not sure if its on the middle of 2018 maybe early 2019.
